Worm:VBS/Jenxcus.A Description

Worm:VBS/Jenxcus.A is a Windows worm that attempts to compromise the infected PC’s security to grant criminals control over it, in a fashion identical to that of a stereotypical backdoor Trojan. Even with Worm:VBS/Jenxcus.A seemingly replaced by Worm:VBS/Dunihi.A, an upgrade to it with additional command support, Worm:VBS/Jenxcus.A still is a major security risk for any computer compromised by Worm:VBS/Dunihi.A, with the potential for installing other threatening software or allowing criminals to access sensitive information. Anti-malware solutions should be engaged for removing Worm:VBS/Jenxcus.A whenever it’s necessary, and malware researchers particularly encourage scanning any removable devices that may be compromised by Worm:VBS/Jenxcus.A for the purposes of self-distribution onto new systems.

The Ways Jenxcus Puts a Jinx on Your Computer

Along with its heir apparent, Worm:VBS/Dunihi.A, Worm:VBS/Jenxcus.A is part of a rise in Visual Basic-based worms targeting Latin American countries with attempts to compromise PCs. Early attacks were targeted at specific institutions, although Worm:VBS/Jenxcus.A (also referenced as VBS_JENXCUS) now appears to be distributed with less discrimination than previously, and may affect casual PC users. Worm:VBS/Jenxcus.A’s choice of Visual Basic as a coding language makes Worm:VBS/Jenxcus.A an unlikely threat for non-Windows computers, although malware experts find that most versions of Windows may be compromised through Worm:VBS/Jenxcus.A.

Worm:VBS/Jenxcus.A only includes support for a scant handful of commands, but these functions are sufficiently broad that they still possess great potential for harming your PC.

Duplicating itself on removable devices such as USB drives. Worm:VBS/Jenxcus.A duplicates itself by creating risky LNK files that take the place of various native files on the device, with the latter hidden (by adding the ‘System’ flag, which makes the affected file invisible on default Windows settings).

Deworming a PC that’s Had a Brush with Old Malware

Worm:VBS/Jenxcus.A doesn’t have as many attack features at its command as many other worms, including its apparent successor, Worm:VBS/Dunihi.A. Nonetheless, any kind of backdoor vulnerability is a high-level PC security issue that should be remedied as soon as possible. While malware researchers continue to recommend using dedicated anti-malware tools for removing worms like Worm:VBS/Jenxcus.A, any anti-malware system scans in use also should cover removable devices that could be compromised by Worm:VBS/Jenxcus.A’s LNK files.

Symptoms of Worm:VBS/Jenxcus.A’s presence primarily are limited to the changes Worm:VBS/Jenxcus.A makes to the aforementioned removable devices. Files that don’t perform their intended functions, show unusual date stamps or are accompanied by unrecognized new files (such as a randomly-named VBScript file) are some of the most obvious signatures. However, backdoor attacks often don’t show symptoms of their presence, even while they dismantle your PC’s security wholesale.

Worm:VBS/Jenxcus.A Automatic Detection Tool (Recommended)

Is your PC infected with Worm:VBS/Jenxcus.A? To safely & quickly detect Worm:VBS/Jenxcus.A we highly recommend you run the malware scanner listed below.

The Threat Meter is a malware assessment that SpywareRemove.com's research team is able to give every identifiable malware threat. Our Threat Meter includes several criteria based off of specific malware threats to value their severity, reach and volume. The Threat Meter is able to give you a numerical breakdown of each threat's initial Threat Level, Detection Count, Volume Count, Trend Path and Percentage Impact. The overall ranking of each threat in the Threat Meter is a basic breakdown of how all threats are ranked within our own extensive malware database. The scoring for each specific malware threat can be easily compared to other emerging threats to draw a contrast in its particular severity. The Threat Meter is a useful tool in the endeavor of seeking a solution to remove a threat or pursue additional analytical research for all types of computer users.

The following fields listed on the Threat Meter containing a specific value, are explained in detail below:

Threat Level: The threat level scale goes from 1 to 10 where 10 is the highest level of severity and 1 is the lowest level of severity. Each specific level is relative to the threat's consistent assessed behaviors collected from SpyHunter's risk assessment model.

Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.

Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.

Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.

% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.
